Title: Reorientation de donnees en cache
Inventor: Gay Allen Arthur
IPC: G06F12/00
Filed: 2017-05-26
Abstract: La présente invention concerne une technologie portant sur la réorientation de données expirées en cache lorsqu'aucune donnée non expirée n'est disponible. Des données non expirées en cache sont utilisées en réponse à une requête lorsque de telles données existent. Si de telles données n'existent pas, par ex. dans un service frontal de données, alors une tentative d'obtention des données demandées d'un autre service de données (par ex. secondaire) est effectuée. Si la tentative échoue, et que des données expirées en cache existent, les données expirées en cache sont renvoyées en réponse à la requête, par ex. plutôt que de renvoyer une erreur. Un service de données secondaire peut, de manière similaire, renvoyer des données expirées de cache lorsqu'il ne peut obtenir ailleurs de données non expirées demandées. Il est possible d'entrer dans un mode d'urgence dans lequel des données, qu'elles soient expirées ou non, sont renvoyées d'un cache lorsque de telles données existent, comme lorsqu'on sait par avance qu'une tentative d'obtention des données ailleurs est futile.
